FRANK C. SXVEENY, OF TOLEDO, OHIO, ASSIGNOR TO THE WILLYS OVERLAND (10., OF TOLEDO, OHIO, A CORPORATION OF OHIO ACCELERATOR PEDAL Application filed November 27, 1929.

This invention relates to control pedals and more particularly to pedals that are used for controlling accelerators of automotive vehicles.

One of the objects of the invention is to provide an accelerator pedal which will not be afiected by road vibration during the opration of the vehicle.

Another object of the invention is to ride an accelerator the foot of the operator.

Other objects will appear from the description to follow, in conjunction with which I have shown a preferred embodiment pro of the invention in the accompanying draws ing, in which Figure I is an elevation partly in section, of the improved accelerator shown in position on the floor of a vehicle.

Fig. H is a view of the accelerator supporting bracket.

Fig. III is a perspective view of the heel plate.

Fig. IV is a perspective view of the toe plate.

Fig. V is a sectional view taken on lines VV of Figure I.

The ordinary accelerator pedal for automobiles is a spring loaded pedal arranged. on

the toe board adjacent the operators ioot in position to be depressed thereby. This type ot'accelerator pedal is objectionable in that when the vehicle is driven over rough roads the pedal is intermittently depressed and released because of the inability of the operato-r to maintain his foot in a fixed position. Various attempts have been made to provide an accelerator pedal that will remove this objectionable feature, but it is believed that the pedal shown and described herein is superior to others which have been heretofore devised.

In the drawing I have shown a floor board and a toe board 12 through which projects a rod 14 that is connected with the throttle (not shown). A toe plate 16 is connected to the rod ll'at its forwardend and has a hinge connection to bracket 18 at The toe plate 16 is prefan offset portion 17 ad pedal that will support tilting of the heel pivotally Serial No. 410,114.

jacent the bracket 18 so that the heel. plate 20 which is also hinged to bracket 18 may overlie the toe plate 16 and normally have its upper surface in the same plane. A pad 22, which is preferably formed of rubber or fabric, extends from end to end of the two plates and is provided with flanges 24 which grip the undersides of the plates 16 and 20 and normally hold them in alignment, the inherent flexibility of the pad permitting slight relative movement between the two. The heel plate 20is hinged to the bracket 18 at approximately its middle point so that pressure applied on opposite sides of pintle 26 will have little tendency to tilt the heel plate on the bracketl8 that is secured to the floor board 10 by screws 19. When the pedal hereinbetore described is used to operate a vehicle, the throttle rod 14 may be moved the desired amount by'rocking both plate 1.6 and plate. 20 as a unit about their coincidental hinge axis 26. Road shocks will cause the operators foot to press upon the pedal as a whole, and these forces will be impressed upon the bracket 18 with little tendency to rotate 7 plate 20 will not affect toe plate 16, because of of the flexible pad 22,

the position of the the damping action and the control of roads will be more positive than that resulting from ordinary accelerator pedals.

lVhile I have illustrated and described one embodimentot the invention, is understood that various changes may be made without departing from the spiritof the invention and I, therefore, wish to be limited only insofar as I have included such limitations in the following claims.

I claim:

, 1. A control pedal for attachment to the floor of a. vehicle,comprising a bracket secured to the floor, two plates separately pivoted to the bracket with the pivotal axes in alignment, and a unitary lying and secured to both plates.

2. A control pedal for attachment to the floor of a vehicle comprising a bracket secured to the floor, a pair of plate members separately hinged to the bracket, said mem the vehicle over rough flexible pad overbers having their hinge axes coincidental, and a unitary flexible pad overlying and secured to both plate members.

3. A control pedal for attachment to a vehicle floor comprising a bracket secured to the floor, a heel pedal plate hinged to said vehicle floor comprising a bracket secured to the floor, a toe plate having an offset portion hinged to the bracket, and a heel plate hinged intermediate its ends to the bracket, said heel plate having its forward portion overlying the offset portion of the toe plate.

6. A control pedal forattachment to a Vehicle floor, comprising a bracket, a heel plate hinged to the bracket, a toe plate hinged to the bracket, and a unitary flexible pad overlying both plates, said pad having flanges in engagement with the under side of both plates whereby both plates are held normally in alignment.

In testimony whereof, I afiix my signature.

FRANK C. SWEENY.
